We have partial success. It didn't shift at first. So I kept driving around and got it to go to second , then third. I drve it around, starting and stopping. It seemed to get better as we drove. I thought it was doing good so we took it out on the freeway. The overdrive as well as the rest of the shifts are crisp. When it locked the converter it felt like anothe gear. I am pretty pleased. We will do some adjustments and get back. But as of now it is mobile.

It kind of hangs in first. I took the heavy spring out of the small weight side of gov and replaced it with the light spring from the heavy weight side. I left the heavy without a spring like a brf has. This appears not to work as it doesn't shift from 1-2 until 25-35 mph at light throttle. I will drop pan and put light spring back in heavy weight side. I think I will leave the light spring in light weight side and probably pin the heavy side like I did the light side.
Where does the computer get a signal of how fast car is travelling? I have an autoxray scan tool but its mph coincides with the speedo so I'm not sure either is accurate.
If I didn't have this job everyday I could make a lot more progress.

Well, that explains why the Speedo and scan tool match up. Got the pan off, modded governor back to stock. Still on the jack stands. Volleyball tonight. Will try to get it out for a test tommorrow. I did run it through the gears on the stands and it seemed to shift sooner. We'll know as soon as I make time for a test drive. At least softball season is over.

Well, we have what I think is success. Put the gov back to AA stock and it is smooth as silk til you tickle the go pedal. Then I'm not sure as it is fairly traction limited, though going to third, od and the converter lock up is firm. I an stoked. Gotta get my stickies mounted on my new(bought them used about ten years ago ) drag star wheels and a trip to the track to see where full throttle shifts are. Very excited.

Give me a call when you decide to go to the track Rich. I might be able to join you. :cheers:

Well, still haven't made it out to the track. I did get the car out yesterday and made a couple blasts with gauge on the trans.

I am pretty pleased with the pressures. It seems to hold 120-150 at light to medium throttle through the gears. At full throttle it stays between 240 and 270 psi. With a good blast from a light it stayed steady at 270 through the shift to third and I let out. I really need a trip to the track. It has never shifted this well. I can't believe I waited so long to build one. The ck book is required reading imo. I didn't do everything it suggested but as has been pointed out, it is one man's ideas.

I can't emphasize enough the help from ttype6, Don Wang, David Husek, Jake Shoemaker, Bruce , Vince Janis, Lonnie Diers , Chris K and several others who post at turbobuick.com in the trans section. I read through all 600 pages  and took a lot of notes.  I am also thankful to the engineer at sonnax who answered questions about their products and the 2004r.

We will see how long this one will stay together. I hope to have enough budget for the next one to have a billet shaft forward so I can dual fees the direct clutches.

If you have any questions let me know.

What did you use to measure temps? Where did you mount it?

I am measureing trans pressures. I haven't looked into temps yet. I think I would want it in the pan or one of the cooler lines if I did. Maybe on the drain bung on one of those cast pans.

the best place to mount a tranny temp sensor is in the outlet line to the cooler as that point shows you how hot the fluid got whereas the pan shows you the "cooled" temp.....the easiest point may be the pan, though :)

A lot of broken parts does not make you a racer; it makes you a slow learner.

The pan catches all the fluid after it goes through the tranny though Steve. The outlet only tests after it goes through the pump.

Rich, thanks for taking the time to do this. It's a great pictorial for the first timer/learner and shows what their up against. I could have swore Jakeshoe had something similar but I can't find it. I remember it having some good pics as well, disassembly ect... I think it got cut a little short for some reason though.
